3 Claims.

This invention relates to mountings for motor cycle pillion seats.

Pillion seats are usually rigidly supported on the rear axle and frameof a motor cycle, with the result that when a pillion passenger iscarried the unsprung Weight is increased very conattached to the rearwheel mounting.

Preferably the support comprises a pair of shock-absorbing devicesconnected to the rear wheel mounting on opposite sides of the wheel,

pression on vice.

Also it is preferable that the rigid member is rigidly connected to thespring main frame of the motor cycle in a position adjacent the saddle.

a mounting for motor cycle pillion seats showing the manner ofattachment of the seat to the frame and wheel support of a motor cycle,and Fig. 2 is a similar view of another embodiment of the invention.

The invention will now be described with reference to Figures 1 and 2 ofthe accompanying drawings which illustrate two difierent embodiments. Ineach embodiment the rear Wheel of a motor cycle is shown as having aresilient suspension, but whilst such a suspension is preferable amounting for a pillion seat in accordance with the invention may beemployed on a motor cycle having a rigidly mounted rear Wheel.

The rear frame member I of a motor cycle supports the saddle 2. The rearwheel 3 is resiliently mounted by means of a radius arm 4 and a shockabsorber 5 disposed on each side reaction plate 6.

A lug 8 is fixed to the saddle frame and is thus rigidly connected tothe main frame.

is pivotally connected at its seat to the reaction plates 6 by means ofa quick release fastener I2. The fastener I2 may comprise a bolt fromwhich the nut may shock absorber ID from the lug I3.

Each shock absorber comprises co-axial inner and outer telescopicmembers and an inner anelement carried by the inner memher andassociated with means for subjecting it to compression on expansion orcontraction of the shock absorber. Shock absorbers of this constructionare described in co-pending application Ser. No. 98,420 filed June 11,1949.

The hole I4 is so located that when the shock absorbers ID are swungabout their bolt II, the fasteners I2 can be aligned with and fastenedin said hole. Thus if the motor cycle is to be ridden with the pillionseat unloaded the shock absorbers It may be disconnected from thereaction plates 6 and connected to the lug it. This is particularlyadvantageous in the case of a motor cycle with a resilient rear wheelsuspen" sion, for, whereas the shock absorbers have the propertiesrequired to give comfortable riding for a pillion passenger, excessivevibration of the pillion seat may occur if it is unloaded and if itsresilient support cannot be disconnected from the resilient wheelsuspension.

In the embodiment shown in Figure 2 the pillion seat is pivotallyconnected at its front end by means of the bolt 9 to a bracket I5 whichis secured to the rear mudguard I6 of the motor cycle. The rear end ofthe pillion seat is supported by shock absorbers ID as herein described.

Having described my invention what I claim 1. A motor cycle whichcomprises a frame and saddle, a resilient mounting on said frame for arear Wheel, a pillion seat pivotally mounted at its front end on theframe of the motor cycle, a resilient support pivotally attached at itsupper end to the rear end of the pillion seat and detachably secured atits lower end to the rear 7 wheel mounting and a lug secured tothe-motor cycle frame to which the lower end of the resilient supportmay be secured when detached from the rear wheel mounting. V

2. The motor cycle of claim 1 in Whichthe front end of the pillion seatis attached to the saddle of the motor cycle.

3. A motor cycle according to claim 1 wherein the resilient supportcomprises a pair of shock absorbing devices disposed one on each side ofthe rear Wheel. 7
